What happens if we tell our youth, "No, you can't have cross-sex hormones?" You have to go through the puberty of an unwanted gender, which could have been avoided if you had cross-sex hormones, you could have had puberty blockers, which would stop the puberty from going forward until you could take the cross-sex hormones, more like the gender body that you want to have. The harm done is that it can create trauma in living in a body that is so alien to you and spoils any of your chances of moving gracefully in the world in your affirmed gender, increases the chances that you will always feel like a freak. For example, a girl's Adam's apple. Girls are not supposed to have, which could have been avoided if you had first done puberty blockers, and then added the hormones of the gender you identified as being. This is the kind of harm. I would ask any of you to imagine this, suppose you grew up and one morning and you saw you were growing an elephant nose. You were horrified. What am I doing with an elephant nose? I want a people nose. That's how a lot of Transgender youth feel about their puberty. When Transgender boys start to grow breasts, when Transgender girls start to grow whiskers; this as if they had an elephant nose on their face. Some kids are so horrified that they try to kill themselves. We would never want that for a child or teen. So if we can avoid that by offering them services to match their bodies to their minds and identities, that will be a harm reduction.
